According to the distance between each element with each cluster center? Yes, for each element you want to compute the neighbours of, you just have to compute its distance to each cluster center. Then you keep the closest clusters. Will you keep several clusters for each element for searching nearest neighbours? Thanks. Yes generally you will. It depends on how many neighbours you want, and how you allow for approximations in the results.
